Surveying system
a technology of a surveillance system and a prism, applied in the direction of distance measurement, instruments, using reradiation, etc., can solve the problems of inability to carry out surveying operations using the prism, the optical reflection point of the prism cannot be directly installed at the measuring point, and the pole cannot be vertically adjusted, so as to reduce the working time and improve the working efficiency.

first embodiment
[0034]First, by referring to FIG. 1, a description will be given on a surveying system according to the present invention.
[0035]A surveying system 1 has a surveying instrument 2 and a target instrument 3. The surveying instrument 2 has a first surveying unit 5 provided on a tripod 4 and a second surveying unit 6 provided on the first surveying unit 5 integrally with the first surveying unit 5. The first surveying unit 5 is a total station, for instance. The second surveying unit 6 is a uniaxial laser scanner which performs a rotational scan in a vertical direction with one axis, for instance. It is to be noted that the second surveying unit 6 may be provided on a side surface of the first surveying unit 5.
[0036]The target instrument 3 has a pole 7 with a conical lower end portion and a target plate 8 mounted on an upper end of the pole 7. The target plate 8 is a rectangular plate material, for instance, and a surface is painted by a color with high reflectance such as a white paint,...
second embodiment
[0094]Next, by referring to FIG. 8, FIG. 9 and FIG. 10, a description will be given on the present invention. It is to be noted that, in FIG. 8, FIG. 9 and FIG. 10, the same components as shown in FIG. 5, FIG. 6 and FIG. 7 are referred by the same symbols, and a detailed description thereof will be omitted.
[0095]In the second embodiment, a target instrument 3 is constituted by a pole 7, a prism 12 and a target plate 59.
[0096]The target plate 59 has a triangular prism shape on which the pole 7 is provided on one end portion, and a lateral cross-section has an isosceles triangular shape, for instance. Further, the target plate 59 has reflection surfaces 61a and 61b formed on two surfaces by two sides with an equal length. The prism 12 is provided on a ridge line 62 formed by the reflection surfaces 61a and 61b in such a manner that the ridge line 62 is directed toward the surveying instrument 2. It is to be noted that the lateral cross-section of the target plate 59 does not have to b...
third embodiment
[0108]Next, by referring to FIG. 11, a description will be given on the present invention. It is to be noted that, in FIG. 11, the same components as shown in FIG. 5, FIG. 6 and FIG. 7 are referred by the same symbols, and a detailed description thereof will be omitted.
[0109]In the third embodiment, a target instrument 3 is constituted by a pole 7, four target plates 66a to 66d provided on an upper end the pole 7, and an omnidirectional prism 67 provided on upper ends of the target plates 66a to 66d. The target plates 66a to 66d are arranged in parallel with the axis of the pole 7 and radially around the pole 7 as a center, and provided at an equal angular interval (90°).
[0110]The target plates 66a to 66d are plate-like shaped members elongated in an up-and-down direction, and reflection surfaces 68a to 68h are formed on both surfaces, respectively. It is to be noted that, in FIG. 11, only the reflection surfaces 68a and 68b are illustrated.
[0111]Further, a ridge line 69a is formed ...
